Improve comments in .env.base file
Created by: player1537
The base environment file should be made more descriptive, so that it includes better descriptions of the purpose of each variable as well as a default or typical value.
Additionally, it needs to include the
TEST_INTERPRETER_ARGUMENTS variable and a description of how to use the comma separated parts of the list.
Lastly, it probably shouldn't use
*_INTERPRETER_* and instead
*_PYTHON_* since it's only expecting a Python interpreter, which also means the name isn't needed.
